Metatrader 4 EX4 is a closed file format of MetaQuotes company, used as compiled Expert Advisor (trading program inside Metatrader 4) or Metatrader 4 library output binaries.
Looking for any information, at first, if you know something about licensing requirements or whatever, because no information available on web and it is not so easy to communicate with MetaQuotes directly.
Looking for someone who already worked inside MetaQuotes or a Broker's IT branch or anything and can give me a full file format specification somehow.
Or, alternatively, looking for a company who sells a licence of EX4 format specification.
Anything other that works.
